The primary function of the HDMI transmitter is to implement the HDMI formatting of the input video and audio data, and interface to a serializer for direct transmission onto the HDMI cable. This IP core supports HDCP authentication and synchronization, identification of the RX capabilities via E-EDID on the DDC, hot plug detection, and a simplified implementation of the CEC protocol.
The IP is composed of an HDMI 1.4 core and its physical Layer devices (PHY) in 65nm, 40nmLP, and 28nmLP technologies.
